Objective: To examine the development of recurrent urinary tract infections (UTIs) in boys who have undergone hypospadias repair., Materials and Methods: We retrospectively reviewed the records of all boys who had recurrent UTIs after primary or redo tubularized incised plate (TIP) or transverse island flap (TVIF) repairs, between 1998 and 2009. Data on age, operating details, postoperative complications and imaging studies were collected. We attempted to identify risk factors for recurrent UTIs after hypospadias repair., Results: During the study period, 43/2249 boys (1.91%) were diagnosed with recurrent UTIs after hypospadias repair. The boys' mean (range) age at repair was 14 (6-24) months and the median (range) follow-up was 6.5 (1.5-11) years. Primary TIP and TVIF were performed in 47% (20/43) and 35% (15/43) of the boys, respectively. Redo surgeries were performed in 18% of the boys (8/43). The initial meatal location was proximal in all TVIF and redo repairs, and in one of the TIP repairs. Postoperative voiding cysto-urethrography, ultrasonography and dimercapto-succinic acid (DMSA) scans were performed in 58% (25/43), 90% (39/43) and 19% (8/43) of the boys, respectively. Abnormalities were noted. Of those boys who underwent a TVIF repair, urethral diverticula were seen in 47% (7/15) and urethral fistulae were also seen in 47% (7/15). Conversely, in those who had a TIP repair, an elevated PVR and vesico-ureteric reflux were more common; they were found in 40% (8/20) and 50% (10/20) of patients, respectively., Conclusions: The pathophysiology of recurrent UTI is multifactorial, but postoperative complications seem to vary with type of procedure. Recurrent UTIs after hypospadias surgery should prompt a specific assessment for potentially functionally relevant and correctable anatomical abnormalities., (© 2013 The Authors.

Objective: To identify the outcome of nephrectomy and predictors of hypertension (HTN) resolution in children with poorly functioning unilateral kidneys (differential renal function, DRF of < 15%), as concurrent HTN is often an indication for nephrectomy., Patients and Methods: Over a 7.5-year period, a single centre retrospective analysis of 89 children with unilateral nonfunctioning/poorly functioning kidney who underwent nephrectomy was conducted. Preoperative HTN was present in 18 children (20.2%). The childrens' characteristics (age, sex, body mass index, pathology, side), cause of nonfunction, diagnostics including preoperative proteinuria (dipstick) and DRF (nuclear scan), pathological features of specimen and follow-up were recorded., Results: The mean (median; range) age at nephrectomy was 6.8 (5; 0.333-14) years with a mean (median; range) follow-up of 2.4 (3; 0.083-5.5) years. The mean (median; range) DRF was 6.5 (1; 0-15)%. Twelve of 18 children (67%) resolved their HTN. Age at nephrectomy, sex, side of nonfunctioning kidney and surgical approach (78% laparoscopic nephrectomy) did not correlate with HTN resolution. Persistence of HTN seemed to correlate with residual function of more than a DRF threshold of 5% (P = 0.05), the presence of preoperative qualitative proteinuria by dipstick (P = 0.03) and inflammation on pathology., Conclusions: HTN resolved after nephrectomy for poorly functioning unilateral kidney in most of the children. Persistence of HTN is probably multifactorial. Ipsilateral residual function before nephrectomy, preoperative proteinuria and pathological features of nephrectomy specimen may serve as clinically useful markers for outcome prediction., (© 2010 THE AUTHORS.

Objective: To describe a suprascrotal technique of testicular prosthesis insertion that obviates the difficulties and complications associated with either the inguinal or scrotal approach, as although the insertion of a testicular prosthesis is common there are few reports of the various techniques of insertion, associated complication rates, and patient satisfaction., Patients and Methods: Eight males (aged 14-26 years) who had had a previous orchidectomy, had a testicular prosthesis inserted using a suprascrotal incision. A 2-cm semilunar incision is made just above the scrotum, 2-3 cm lateral to the penis ('wink' incision). The prosthesis is inserted after developing the intrascrotal space with blunt dissection. All patients tolerated the procedure well and all were outpatient procedures., Results: After a median follow-up of 12 months, all patients were satisfied with the aesthetics of the prosthesis. Incisions were hidden by pubic hair. There were no wound infections at the incision site, and no reports of any pain or discomfort associated with the prosthesis., Conclusion: The 'wink' incision is an attractive alternative for inserting a testicular prosthesis; the advantages of the suprascrotal approach include: (i) the incision is hidden by pubic hair; (ii) no difficult dissection through fibrotic tissue in patients who have had previous inguinal surgery; and (iii) avoidance of direct contact between the prosthesis and suture line, minimizing the risk of infection, erosion and postoperative pain, while maintaining a pouch of adequate size.

Objective: To describe a technical modification that facilitates dorsal skin closure, improves cosmesis and eliminates chordee recurrence secondary to contracture of the dorsal penile skin in the repair of epispadias., Patients and Methods: Eleven patients with penopubic epispadias (mean age 1.8 years) had the epispadias repaired using a modified ventral penile skin flap. Four patients had isolated epispadias and seven had had a previous primary closure of bladder exstrophy. Nine patients underwent the Cantwell-Ransley technique, leaving the meatus in a glanular position. Two patients were repaired using the penile disassembly technique of Mitchell and Bägli, because they had a short urethral plate. A ventral island skin flap was fashioned, starting at the base of the penis. Dissection was carried ventrally into the scrotum to allow for adequate dorsal flap transposition. The flap was rotated laterally to shift the suture line from the midline and to cover the dorsal aspect of the penis with untouched penile shaft skin. Redundant ventral foreskin was discarded., Results: All patients had an uneventful course after surgery. Dorsal penile skin was viable in every case and no patient developed recurrence of chordee or a urethrocutaneous fistula. The cosmetic result was excellent in all patients., Conclusions: Dorsal skin closure using lateral rotation of ventral penile skin flap improves cosmesis after epispadias repair and eliminates the recurrence of chordee secondary to midline dorsal scarring.
